Weatherwatch: Charles Keeling's CO2 curve shows drastic rise in 60 years

Scientist's measurements begun 60 years ago show relentless rise of CO2 in the atmosphereA remarkable run of observations began 60 years ago at a weather station high on a volcano in Hawaii. Charles Keeling began monitoring carbon dioxide in the clean air at 3,400 metres (11,150ft) on Mauna Loa, far away from vegetation and urban pollution. His first measurements in 1958 showed 315 parts per million (ppm) of CO2 in the atmosphere, and what caught him by surprise was that every year after that the levels of CO2 rose relentlessly in an upward curve, thanks to the carbon pollution pumped into the Earth's atmosphere.
